1. turning a door knob
a. supinator: supinates forearm at radioulnar joints; innervation: deep radial nerve
b. pronator teres: pronates forearm at radioulnar joints and weakly flexes forearm at elbow joint; innervation: median nerve
c. pronator quadratus: pronates forearm at radioulnar joints; innervation: median nerve
2. throwing a baseball overhead
a. latissimus dorsi: extends, adducts, and medially rotates arm at shoulder joint; draws arm inferiorly and posteriorly; innervation: thoracodorsal nerve
b. biceps brachii: flexes forearm at elbow joint, supinates forearm at radioulnar joints, and flexes arm at shoulder joint; innervation: musculocutaneous nerve
c. supraspinatus: assists deltoid muscle in abducting arm at shoulder joint; innervation: suprascapular nerve
3. kicking a ball
a. vastus medialis: extend leg at knee joint; innervation: femoral nerve
b. rectus femoris: extend leg at knee joint and flexes thigh at hip joint; innervation: femoral nerve
c. gluteus medius: abducts thigh at hip joint and medially rotates thigh; innervation: superior gluteal nerve
4. doing sit-ups
a. rectus abdominis: flexes vertebral column, especially the lumbar portion and compresses abdomen to aid in defecation, childbirth, urination and forced exhalation; innervation: thoracic spinal nerves T7-T12
b. transversus abdominis: compresses abdomen; innervation: thoracic spinal nerves T8-T12, iliohypogastric nerve and ilioinguinal nerve
c. rectus femoris: extend leg at knee joint and flexes thigh at hip joint; innervation: femoral nerve
5. walking
a. tibialis anterior: dorsiflexes foot at ankle joint and inverts (supinates) foot at intertarsal joints; innervation: deep fibular (peroneal) nerve
b. gastrocnemius: plantar flexes foot at ankle joint and flexes leg at knee joint; innervation: tibial nerve
c. soleus: plantar flexes foot at ankle joint; innervation: tibial nerve
6. breathing
a. diaphragm: contraction (increases vertical dimension of thoracic cavity; inhale) and relaxation (decreases vertical dimension of thoracic cavity; exhale) of diaphragm; innervation: phrenic nerve, which contains axons from cervical spinal nerves C3-C5.
b. external intercostals: contraction (elevates ribs and increases anteroposterior and lateral dimensions of thoracic cavity; inhale) and relaxation (depresses ribs and decreases anteroposterior and lateral dimensions of thoracic cavity; exhale); innervation: thoracic spinal nerves T2-T12.
c. internal intercostals: contraction (draws adjacent ribs together to decrease anteroposterior and lateral dimensions of thoracic cavity; forced exhalation); innervation: thoracic spinal nerves T2-T12.
